If you receive a drawing from a Civil3D user, there is a possibility it contains CogoPoints that appear locked. You can’t move them, you can’t rotate them, etc. Since you don’t have the Survey Database you can’t unlock them like the original creator did. If this happens to you, read on.

The process of importing contours from shapefiles is actually a two step process, since the results from Autodesk’s MAPIMPORT command does not elevate the resulting polylines. This is a step-by-step procedure on how to take a shapefile of contours to elevated polylines in AutoCAD (Map/Civil3D).

Like many things in Civil3D, they can be done but how it’s done isn’t so obvious. In the process of adding a DEM surface to your drawing you may notice that you can’t project it to another coordinate system (that of the drawing). Here is a step-by-step procedure including assigning a coordinate system to the current drawing.

ESRI Shapefiles are not just the SHP file. While some importers can import the geometry from just that one file, a lot remains missing. That’s why it’s important to send the package, not just a single SHP file.

AutoCAD 2017 introduced a change to the way it handles the background in icons for ribbons, menus, etc. For many years the longstanding tradition was to allow RGB 192,192,192 to represent transparency in icons. Now old custom CUIX files display with an undesirable light gray background.

Contrary to popular belief, command line tools are not dead. This one (well known across the world as GDAL) should be a part of any well prepared mapping professionals toolbox. Here we will explain how to get started with it and some of it’s uses.
